IMPROVEMENT IN PLOW-COLTERS.

Specification forming part of Letters Patent N0. 210,047, dated November 19, 1878; application filed October 21, 1878.

To all whom it may concemm Be it known that I, THOMAS MEIKLE, of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Golters of Plows; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which I sists in a colter or cutter so constructed as to be attached to the frog of a plow in connection with the mold-board.

A is the standard of aplow. B is the moldboard. 0 is the point. D is my invention, representedin its position in the plow at Fig. 1.

This colter is constructed substantially as represented, and is so formed as to present a thin, sharp, strong cutting-edge, and at its rear part abuts or shoulders by a flange or projection firmly against the standard of the plow, and, extending rearward on the moldboard side of the plow, overlaps a portion of the frog of the plow, and is secured to the same by means of bolts.

The colter D is made of cast-steel or other suitable metal, and at D presents a long, thin,

sharp, and strong cutting-edge, which extends from the point of the plow to the top of the.

mold-board.

At D there is a flange-formed projection engaging the plow-standard at A, which provides for a firm seat for the colter, and the colter therefrom extends rearward over the frog of the plow, and is attached to the frog by the bolts d and d.

The frog is attached to the standard, as is commonly done, by the bolts to, and the moldboard is attached to the frog by the bolts 6 and b and properly jointed to the colter.

I am aware that colters of plows have been so constructed as to rest against the standard of the plow, and to be attached, some to its land-side and others to its mold-board side; but

What I claim as new, and desire to secure by Letters Patent. is-- The colter D, constructed with the shoulder 1) engaging the standard, and the flange D extending rearward over the frog on the mold-board side of the plow, perforated with holes for the bolts 01 and d for attaching it to the frog, in combination with the standard andfrog of the plow, and so constructed as to form proper joints and inclinations with the point and mold-board, as and for the purposes substantially as set forth.

In testimony that I claim the foregoing as my ownI affix my signature in presence of two witnesses.

. THOS. MEIKLE.
